Google has a walled garden as well.

For the Smartphone OS, maybe yes. But not for the Hardware, Services and the rest of its *entire* ecosystem.

Google is not the savior for that industry, it's just the only real alternative (until some regulation hopefully enables a competitor to rise)

Talking to my less techy friends, they won't even consider the thought of moving just because their purchases won't carry over.

Yes, hence the applause for everyone who just TRIES.
